Echo of Medivh dies bug

I was doing the Return to Karazhan speedrun, and after talking to the Echo of Medivh, he does the RP as normal. However, when he starts fighting the image of Arcanagos, the dragon just one shots him (https://imgur.com/a/y0jZY5S). Thus it becomes impossible to get Nightbane to actually spawn.

Same here. Has happened on 2 characters now. First one was Tuesday, GM said they couldn’t do anything and I probably did something wrong. Did it again today on another character and the same thing happened.

Same happened to me on 3 of my toons. Blue dragon is one shoting medivh now. I collected crystals as normal and talked to his echo and heard the rp, then medivh takes the fire ball to the face and dies now instead of walking it off.
